Honeywell LG1093AA24 UV Flame Sensor

Honeywell LG1093AA24 is a solar-blind ultraviolet flame sensor adopting Geiger-Mueller tube technology. It detects ultraviolet radiation generated by hydrocarbon flames, transmitting pulse signals to flame amplifier and burner management control system for flame supervision.

This sensor is equipped with 4.9-meter Teflon shielded cable and 3/4 inch NPT internal thread mounting interface. It is widely applied on gas turbines, boilers and industrial burners, and serves as critical safety spare parts for power plant combustion protection systems.
